Metallurgy

11/27/2010 8:15 PM

hello all, i have a question about a composite metal. I need to know what type of metal composite can withstand 2000 degrees farenheight for extended periods of time and still be condictive of electrons. thank you for your input.

Well from the description you've given almost any metal will do this. Most metals will no longer be considered solid and therefore incapable of providing any kind of mechanical support. I would also recommend that you do this in a non-oxidizing environment.

would a vaccum provide a suitable enviroment?

That's all your going to specify. My you're lazy.

Well Molybdenum melts at about 4700°F.

A vacuum! Are you serious. I'll grant you that it won't oxidize in a vacuum but now you have to worry about sublimation. A high pressure noble gas will be certainly easier.

Get all of your information together first.

I don't like playing 20 questions.

"2000 degrees farenheight for extended periods of time" is no problem. But the requirement to still be "condictive of electrons" is too much to ask at that temperature. Conjunction, maybe; condiction, no way.

Maybe next year.

You got me here. Silly me I misread what the OP wrote. You're correct, one should not ever expect anyone at 2000°F to be condictive to electrons.

Use the same as in the classical electric bulbs: tungsten or wolfram.

It does not melt it is CONDUCTIVE (current goes through) and resists to high temperature. problem is the convection of the protective gas and the fact that at high temperature atoms become free and go with gas: this is the dark deposit on the bulb.

Nickname is correct...

At 2000F you have very few choices.

Tungsten is a metal that has a high melting point (>6100F), very, very high density(71% greater than lead) and is impossible to machine.

Also very pricey...

Where can you compromise ???

hello im the guy that started this thread, the reason i ask so many questions is because i need to learn, and the best way to do that is to ask ppl who know more about something than i do. What i want to do is succesfully produce heat in a 0 atmosphere enviroment, compress it and move something, with out a liquid or solid fuel source, i have the method down pat i think, after talking with an aircraft engineer, and an areospace engineer, what i need now is to figure out the mats i need to make it happen.
